PROP FOR CARRIAGE-TOPS.

SPECIFICATION forming part of Letters Patent No. 744,219, dated November17, 1903. Application filed December 31, 1902. Serialll'o. 137,230- (Nomodel.)

Too/ll whom, it may concern:

Be it known that I, FRED A. NEIDER, a citi zen of the United States ofAmerica, and a resident of Augusta, county of Bracken, Stateof Kentucky,have invented certain new and useful Improvements in Props for Carriage-Tops,of which the following is a specification.

My invention relates to top-props for carriages in which the bolt of theprop-joint passes through the bow.

- The object of my invention is a bolt which does not split the bow,will not turn therein, and with which the use of reinforcing-clips toprevent the bows splitting are dispensed with. This object is attainedby the means described in the specification and illustrated in theaccompanying drawings, in which- Figure 1 is a side elevation of acarriagetop. ,Fig. 2 is a detail sectional view of a carriage-bow andthe bolt embodying my inven tion upon an enlarged scale. s Fig. 3 is ade tail plan view of apart of a bow, showing the hole made thereinthrough which the bolt is driven. Fig. 4 is a detail view of the sameafter the bolt has been driventherethrough. Fig. 5 is a sectional viewshowing the propjoint complete. Fig. 6 is a perspective View of thesleeve upon which the prop-brace fits. Fig. 7 is a perspective view ofthe bolt.

Referring to the parts, bolt A has two of its sides cut away atdiametrically opposite points, making the bolt in cross-sectionsubstantially in the shape of an elongated rectangle. The screw-threadsare left upon the sides a a. At the end a the bolt is reduced, so thatits end consists of a circle of a diameter equal to the least diameterof the bolt. Bow B has a hole I) bored through it equal in diameter tothe end a of the bolt. The bolt is then driven through hole b, with thelonger diameter of the bolt lying parallel with the.

grain of the how. The effect of this is to spread hole 19 in thedirection of the grain, while the hole in the direction counter to thatof the grain is not affected. Thus there is no tendency to spread thebow apart at the grains, the expanding of the hole in a directionparallel to the grains only crowding the material in that direction andnot affecting the strength of the how, but simply tightening the woodabout; the bolt, so that there is no tendency in it to slip out or torotate in the how. The

bolt not having affected the grain of the bow the splitting of the bowor to hold the bolt from turning therein. After the bolt has been passedthrough the bow as aforedescribed thimble O, which is interiorlyscrew-6o threaded at its upper end, is screwed down over the bolt to bearagainst the bow, and split sleeve D is then placed over the bolt. BraceE is then placed over the sleeve E, and jam-nut F is brought to bearagainst the sleeve D, which is made slightly wider than the brace E, sothat it is held firmly against the thimble O by the jam-nut F andaflords a good journal for the brace E.

What I claim is- 1. In a prop for carriage-tops, the combination of abow, a bolt having two of its sides cut away at diametrically oppositepoints driven through the bow with its longer diameter in a directionsubstantially parallel to the grain thereof, and abrace journaled uponthe bolt, substantially as shown and described.

2. In a prop for carriage-tops the combination of a bolt having two ofits sides cut away'at diametrically opposite points and driven throughthe bow by first forming therein a hole of a, diameter equal to theleast diameter of the bolt, with its greatest diameter parallel to thegrains of the bow, and a brace journaled upon the bolt, substantially asshown and described. 7

3. In a prop for carriage-tops the combination of a'bolt having two ofits sides cut away at diametrically opposite points, the screw-threadsupon the bolt at its longer diameter, a bow with the bolt driventherethrough, the longer diameter of the bolt coming parallel to thegrain of the how, a thimble upon the bolt, a sleeve adjacent to thethimble, a brace journaled upon the sleeve and a jam-nut upon the end ofthe bolt bearing the bow with its longdiameterparallel to the againstthe sleeve, substantially as shown grain of the bow to form a part ofthe propand described. joint, substantially as shown and described. 4.In a. prop for carriage-tops the combi- FRED A.
